Gene Therapy of chronic lymphocytic leukemia (CLL).

Car T-cells are more formally known as chimeric antigen receptors. These cells are genetically modified t-cells that are designed to target tumor cells. These CAR t-cells work by circulating through the blood looking for cells that they can bind to. The receptors of these cells are specifically designed to recognize a pattern that is common cancer. Once they cell comes into contact with the specific receptor, cell will then attack and destroy the cancer, but also can tell the rest of the body that there is a problem. The additional hope is that the CAR-T cells will create memory cells within the body as a normal T-cell. In the simplest explanation, CAR-T cells are genetically modified to attack cells the body would otherwise not recognize.

According to the American Cancer Society (2013) stated, “Leukemia is a cancer that starts in early blood-forming cells” (American Cancer Society, 2013). “Most often, leukemia is a cancer of the white blood cells, but some leukemias start in other blood cell types” (American Cancer Society, 2013). “Any of the cells from the bone marrow can turn into a leukemia cell” (American Cancer Society, 2013). According to the American Cancer Society (2013) stated, “Once this change takes place, the leukemia cells don’t go through the normal process of maturing” (American Cancer Society, 2013). There are changes that leukemia cells can quickly reproduce themselves and not die when they are suppose too (American Cancer Society, 2013). “They survive and build up in the bone marrow, crowding out normal cells” (American Cancer Society, 2013). “In most cases, the leukemia cells spill into the bloodstream fairly quickly” (American Cancer Society, 2013). “Almost all childhood leukemia is acute leukemias” (American Cancer Society, 2013).

Leukemia is cancerous disease that starts in blood-forming tissue such as the bone marrow and causes large numbers of blood cells to be produced and enter the blood-stream (National Cancer Institute, 2008, para. 1). It is one of many complicated cancer diseases that affect all ages and have very negative outcomes if not treated properly, and on time. Within the disease are several different types that affect according to how quickly the disease develops and attacks the body. It could be classified as chronic leukemia, which has a slow progress of getting worse or acute leukemia which usually gets worse quickly. The types of leukemia also can be grouped based on the white blood cell that is affected (National Cancer Institute , 2008, p. 1).

Myelodysplastic disorders (MDS) are conditions that happen when the blood-forming cells within the bone marrow are harmed. This harm prompts low quantities of one or more sorts of platelets. Myelodysplastic syndromes (MDS) are a group of diseases of the blood characterized by a defect in the bone marrow that produces abnormally or insufficient blood red, blood cells white and platelets. MDS is also called pre-leukemia because, over time, can develop into leukemia become acute and should not be confused with Myeloproliferative syndromes.

Myelofibrosis is a bone marrow disorder that leads to a disruption of the body’s ability to produce normal healthy blood cells. A rare form of chronic leukemia, the disease often worsens over time and may cause some patients to develop more serious types of leukemia. Conversely, other people have myelofibrosis and go for years without noticing any symptoms.

Sickle Cell Anemia is a hereditary disease that has a gene that causes red bone marrow in the body to make sickled shapes, when this happens; it causes the red blood cells to die faster. This is what causes Hemolytic Anemia. Older children and adults with sickle cell disease may have very few complications, or have patterns of ongoing problems that ultimately shorten their lives. The most serious and common problems with sickle cell disease are organ failure, fatigue and pain. There are many opportunities and alternatives for treatment and symptom management that a sickle cell patient can consider today.

* HIV belongs to a group of retroviruses called lentiviruses. The genome of retroviruses is made of RNA, and each virus has two single chains of RNA; for replication, the virus needs a host cell, and the RNA must first be transcribed into DNA, which is done with the enzyme reverse transcriptase.

After, the doctor gives further treatments to help prevent the return of the signs and symptoms of the disease after an improvement. Most of patient with acute forms of leukemia can be cured today. It is one of the most curable forms of cancer. Chronic leukemia is detected through a routine blood test before symptoms appear. With this people may not need treatment right away if they are not having symptoms yet, the doctors monitor the disease until treatment is needed. Most of the time it cannot be cured, but it can be controlled.

This is just one of many stories that prove CAR-T cells are a hopeful option for the future. Further research has shown that these cells are not specific to treating leukaemia but also many forms of lymphoma, melanoma, and possibly solid tumours.

The HL disease relapse (DR) was calculated from the time of starting the treatment untill recurrance (relapse) of the disease. On the otherhand the overall survival (OS) was calculated starting from the treatment untill death. The data in our study population showed that 27/100 (27%) is the total number of relapsed and dead HL patients. A total of 16 HL patients (16%) is the known relapsed HL cases in a peiod ranges from minimum of 1 month to 12 years with a median of 3.2 years. About 11 HL patients out of 100 (11%) they died from the diseases, within a period range from 1 month to 12 years. The majority of the studied HL patients died within the first 5 years while minority survive for more than 5 years. The OS median is approximately 3.5

Leukemia is a type of cancer. Cancer is a group of more than 100 diseases that have two or more important things in common. One is that certain cells in the body become abnormal. Another is that the body keeps producing large numbers of these abnormal cells. Leukemia is cancer of the blood ce3lls. When leukemia develops the body produces large numbers of abnormal blood cells. In most types of leukemia, the abnormal blood cells and they do not

There are two types of leukemia in children; acute and chronic. Acute is fast growing leukemia. Within acute leukemia are three categories: acute lymphocytic (lymphoblastic) leukemia (ALL), acute myelogenous leukemia (AML), and hybrid or mixed lineage leukemia. Acute lymphocytic (lymphoblastic) leukemia (ALL) is the most common type of childhood leukemia and develop from early forms of lymphocytes, also known as white blood cells. Specifically, three out of four childhood leukemias are ALL (About Childhood Leukemia). Acute myelogenous leukemia (AML) starts from the myeloid cells that create blood forming cells such as white blood cells (except for lymphocytes), red blood cells, and platelets (About Childhood Leukemia). Hybrid or mixed lineage leukemia are rare forms of childhood leukemia, but can be treated like ALL and AML. On the other end of the spectrum is chronic, or slow growing, leukemia. Chronic leukemia is difficult to treat and are more commonly found in adults than children. There are two types of chronic leukemia: chronic myelogenous leukemia (CML) and chronic lymphocytic leukemia (CLL). Chronic myelogenous leukemia (CML) is not commonly

Despite the promise of such approaches, a number of difficulties remain to be overcome, the most important of which is the need for more efficient systems of gene delivery. No gene transfer system is 100% efficient, unless germ-line therapy is contemplated. During the past two decades, there have been major advances in our understanding of how cancer develops, proving that cancer has a genetic basis (2). A series of genetic abnormalities that accumulate in one cell may result in a pattern of abnormal clonal proliferation. Our growing understanding of the genetic basis of cancer offers new opportunities for the molecular prevention and treatment of cancer. There has been a

There are three techniques that researchers are working on. The first and most common is ex vivo ( or "outside the living body") therapy. The defective cells are removed from the patient and replaced with the normal DNA before returning to the body. This therapy targets the blood cells because many genetic defects alter the functioning of one type of these cells or another. But since blood cells have limited life spans follow-up treatments are required. Future efforts will most likely target stem cells of the bone marrow. Stem cells are ideal for gene therapy because they appear to be immortal. Researchers have obtained stem cells from human bone marrow, but they are having difficulties getting genes into the cell as well as inducing the cells to produce many new blood cells (Anderson, 1995).
